Does Coffee Dehydrate You?

October 25, 2026 · Al-Aqeeq Team

Quick answerNo, not in normal amounts. Caffeine has a mild diuretic effect, but the water in a cup of coffee largely offsets it, and regular coffee drinkers build tolerance. Moderate coffee can count toward daily fluids, though water should still be your main drink.

The science in brief

Studies of habitual coffee drinkers found moderate intake hydrated similarly to water. Very high caffeine doses can increase urination more.

Tips

  • Have a glass of water alongside coffee, as Yemeni and Turkish traditions do.
  • Stay moderate in hot weather or during exercise.
